Thanks everyone, I'll run the race in my old trainers but I'll look on the sweatshop website to find my nearest sweatshop to buy new shoes afterwards. It sounds like the people there will be able to advise me as i don't know anything about what trainers i need.

Hi, I've only been running a few months and am taking part in my first 5K race on Sunday. I could do with getting a decent pair of trainers and i can get to London or anywhere in Herts on Saturday but don't know where to go to get someone who can help rather than a Saturday kid who doesn't know anything about the trainers they sell - any ideas?
